Velocity

Testo offers a range of vane anemometers to assist HVAC technicians, from the pocket-sized testo 410-1/2 to our larger instruments. These devices measure not only flow speed and volume flow, but also temperature. Each data point is displayed through the instruments' easy-to-use digital interfaces. By inputting the duct area, you can gain accurate calculations of volume flow. Some options, such as the testo 417 Large Vane Anemometer, allow you to use funnel settings for exact measurements at ventilator grilles and disc outlets.Also known as thermal anemometers, these instruments Measure air flow velocity, volume flow and temperature. Testo's hot wire anemometers are ideal for measuring the flow in ducts or at duct openings or draughty windows. Did you know: Some of our vane anemometers not only displays flow speed and volume flow but also displays temperature & humidity.
